iPhone Uses Cellular on Wi-Fi? Check Connectivity Assist Before VPN Tests

Cellular usage while Wi-Fi is present does not by itself establish a VPN fault. Identify any cellular assistance before comparing connections.

Check the name on your version

Apple now places Connectivity Assist in Wi-Fi settings, replacing the earlier Wi-Fi Assist in Cellular settings. It can use cellular data when Wi-Fi is poor; older software may show a different location.

Run one controlled comparison

  1. Record iOS version, Wi-Fi, VPN route and starting cellular usage without resetting counters.
  2. Find Connectivity Assist under Wi-Fi, or Wi-Fi Assist under Cellular on older software; note its original state.
  3. For a Wi-Fi-only comparison temporarily turn assistance off. Do not substitute airplane mode when calls must remain available.
  4. Keep the VPN route fixed and compare one small page briefly, noting network switches and disconnects.
  5. Restore your preferred setting afterward. Report weak-Wi-Fi differences to the network provider and preserve logs for continuing disconnects.

Separate usage from tunnel state

A cellular counter cannot prove a request used the VPN, and disabling assistance does not guarantee an uninterrupted tunnel. Yunbao handover behavior has not been measured here.

VPN Works Differently on Wi-Fi and Mobile Data: Compare Networks

Keep device, app, route and destination fixed. Test Wi-Fi and mobile data close together, first directly and then through the VPN. Change only the network so a simultaneous route change does not obscure the cause.
